ABSTRACT:
The present invention is directed to a process for adsorptive separation of carbon monoxide or olefins from gas mixtures using adsorbents, which comprise cuprous compounds dispersed on amorphous oxide or carbon macroporous supports. The compositions are prepared by impregnating cupric compounds on, preferably pretreated, supports with the aid of an aqueous solution of an ammonium salt of a di- or polycarboxylic acid dispersant, such as ammonium citrate, followed by reduction of the cupric compound to the corresponding cuprous compound. The reduction can be performed either by the use of elevated temperature or by the use of a reducing gas preferably carbon monoxide at relatively low temperatures up to 150.degree. C. Methods of synthesis are also disclosed.
